Abstract

In the field of active matrix liquid crystal displays and, more particularly, to microdisplays produced using collective fabrication technologies, a matrix comprises, for each pixel, a transparent electrode and opaque regions resulting from the presence in the pixel of at least one row conductor, one column conductor, and one control transistor for the pixel connected to the electrode of the pixel. The pixel comprises at least three possible geometrical configurations, the position of the transistor with respect to the rows and to the columns being different in the various configurations, the various configurations being distributed in a pseudo-random manner within at least one region of the matrix.
